Direct conversion of rice husk into hydrogen and sodium silicate via alkaline thermal treatment with low‐CO2 emission

open access: yesJournal of the American Ceramic Society, Volume 109, Issue 1, January 2026.
This sustainable process produces clean H2 from rice husk via alkaline thermal treatment with in‐situ CO2 capture. The generated Na2CO3 reacts with rice husk ash (SiO2) to form sodium silicate (Na2SiO3), enabling simultaneous energy production and material utilization.

PtCu catalyst synthesis via Cu oxide‐mediated carbon etching and alloying strategy for enhanced ORR

open access: yesJournal of the American Ceramic Society, Volume 109, Issue 1, January 2026.
Abstract Enhancing both the activity and durability of oxygen reduction reaction (ORR) is essential for the advancement of proton exchange membrane fuel cells (PEMFCs) in practical applications. In this study, we present a novel strategy to synthesize highly dispersed PtCu alloy nanoparticles (NPs) within etched carbon supports using copper oxides seed‐

CVD‐Engineered Ni and FeNi Catalysts on Hexagonal Boron Nitride for Efficient CO2‐Methane Co‐Conversion to Syngas: High‐Performance Alternatives to Traditional Alumina‐Supported Catalysts

open access: yesInternational Journal of Energy Research, Volume 2026, Issue 1, 2026.
This study presents a sustainable approach for mitigating greenhouse gas emissions by converting methane (CH4) and carbon dioxide (CO2) into syngas using nickel‐based catalysts supported on hexagonal boron nitride (hBN), synthesized through chemical vapor deposition (CVD).
